Waste Paper Pulping Process

Nowadays energy saving and environmental protection have been the considerable themes in no matter our daily life or the development of society. Waste paper pulping technology effectively applies this two themes to paper making industry, and it has been more and more significant and prevalent. This article will simply introduce waste paper pulping process for you.

Waste Paper Bales Breaking

The first step of pulping process is breaking waste paper bales. The paper bales is sent to chain conveyor firstly, which can separate the large heavy impurities and reduce the wear to the latter equipment. After that waste paper enters drum pulper to be pulped.

Cleaning and Screening

The purpose of this step is removing various kinds of light and heavy impurities, such as iron wire,stamples, glasses,etc. The waste paper pulp was sent to the cleaner equipment and screening equipment, such as high density cleaner, pressure screen and etc.

Deinking

Sometimes there are ink particles in waste recycled pulp. Deinking can availably and further remove them. The equipment used in this process is flotation deinking machine.

Pulp Beating

The slurry needs to be refined according to the different paper types. For example,the beating degree of toilet paper is about 52%, while the beating degree of culture paper is about 40%.

Cultural paper machine line: Firstly, Raw materials are conveyed by Chain Conveyor into Drum Pulper for pulping. Then, High Density Cleaner helps to remove heavy impurities. What’s more, we need to improve slurry beating degree by using Double Disc Refiner. Eventually, the waste paper turn into fine pulp after a series of screening and deslagging and it will be conveyed into Headbox for paper making.
